Legend:

Before explaining the filter-specific routines and the calling interface of each routine, we provide an overview of the internal interface routines of PDAF. The structure of the internal interface of PDAF is depicted in Figure 1 (For the filter-specific routines, 'X' is the name of the filter algorithm). Shown are only the routines that are relevant for the implementation of a new filter method grouped by type. For a new filter algorithm, new new filter-specific routines (right column of Fig. 1) need to be implemented. These are registered in PDAF by modifying the internal interface routines in the middle column of Fig. 1.
